(Fig. 30)
Kickbacks, skating, bouncing and dropping
Different forces can have an effect on the safe control of
the product.
Skating is when the guide bar glides or moves
quickly across the wood.
Bouncing is when the guide bar lifts off the wood and
touches it again and again.
14
279 - 005 - 27.09.2019
Dropping is when the product drops down after the
cut is made. This can cause the moving chain to
touch a part of the body or other objects, causing
injury or damage.
Kickback is when the end of the guide bar touches
objects and moves rearward, up or suddenly
forward. Kickback also occurs when the wood closes
in and pinches the saw chain during the cut. Loss of
control can result if the product touches an object in
wood.
(Fig. 31)
Rotational Kickback can occur when the moving
chain touches an object at the top of the guide
bar. This can cause the chain to bury into the
object and cause the chain to stop immediately.
The result is a very fast, reverse reaction that
moves the guide bar up and rearward in the
direction of the operator.
(Fig. 32)
(Fig. 33)
Pinch-Kickback can occur when the saw chain
suddenly stops during the cut. The wood closes
in and pinches the moving saw chain along the
top of the guide bar. The sudden stop of the
chain reverses the chain force and causes the
product to move in the opposite direction of the
turn of the chain. The product moves rearward in
the direction of the operator.
(Fig. 34)
Pull-In can occur when the saw chain suddenly
stops when the moving chain touches an object
in the wood along the bottom of the guide bar.
The sudden stop pulls the product forward and
away from the operator, which can easily cause
the loss of control of the product by the operator.
(Fig. 35)
Make sure that you understand the different forces and
how to prevent them before you operate the product.
To prevent kickbacks, skating, bouncing and
dropping
While the engine runs, make sure to hold the product
tightly. Keep your right hand on the rear handle and
the left hand on the front handle. Tightly hold with
thumbs and fingers around the handles. Do not let
go.
Keep control of the product during the cut and after
the wood falls to the ground. Do not let the weight of
the product drop down after the cut is made. (Fig.
36)
Make sure that the area in which you are cutting is
free from blockage. Do not let the nose of the guide
bar touch a log, branch or other blockages while you
operate the product.
Cut at high engine speeds.
Do not overreach or cut above shoulder height. (Fig.
37)
Obey the manufacturer's sharpening and
maintenance instructions for the saw chain.
Only use replacement guide bars and saw chains
specified by the manufacturer.
The risk of kickback is increased if the depth gauge
setting is too large.
Personal protective equipment
Always use the correct personal protective
equipment when you operate the product. The
personal protective equipment does not erase the
risk of injury. The personal protective equipment
decreases the grade of injury if an accident occurs.
Generally, clothes should be close-fitting without
restricting your freedom of movement.
Use an approved protective helmet.
Always use approved ear protection while you
operate the product. Noise for a long period can
cause hearing loss.

2. Pull the choke control out fully.
3. Push the air purge bulb 6 times.
4. Push the choke control in fully.
5. Hold the body of the product on the ground with your
left hand.
6. Put your right foot through the rear handle.
7. Pull the starter rope handle slowly with your right
hand until you feel some resistance.
8. Pull the starter rope handle with force.
CAUTION: Do not pull the starter rope
until it stops. Do not let go of the starter
rope when it is fully extended. Release
the starter rope slowly. If you do not
obey these instructions, it can cause
damage to the engine.
Note: Do not pull the throttle trigger when you start
the engine.
9. Pull the starter rope handle until the engine starts.
10. Hold the rear handle with your right hand and the
front handle with your left hand.
11. Immediately pull the front hand guard rearward in the
direction of the front handle to disengage the chain
brake.
Note: The chain will move.
12. Wait 10-15 seconds.
13. Pull the throttle trigger lightly to set normal idle.
14. Use the product.
To start the engine when the fuel is too hot
If the product does not start, the fuel can be too hot.
Note:
Always use new fuel and decrease the operation
time during warm weather.
1. Put the product in a cool area away from open
sunlight.
2. Let the product cool down for 20 minutes at
minimum.
3. Press the air purge bulb again and again for 10-15
seconds.
4. Obey the procedure to start a cold engine. Refer to
To start a cold engine on page 18
.
To stop the engine
Push the stop switch to stop the engine.
Note:
The stop switch automatically goes back to its
initial position.
To use a spiked bumper
A spiked bumper holds the wood as you cut. The spiked
bumper is a pivot between the engine body and the
guide bar.
1. Put the lower end of the spiked bumper at the
correct felling hinge width.
2. Push against the front handle with your left hand and
lift the rear handle with your right hand.
3. Cut until you get the correct felling hinge width.
Note: The felling hinge must have an equal
thickness.
4. Cut more than half of the diameter and then put the
felling wedge into the saw cut.
To fell a tree
1. Remove dirt, stones, loose bark, nails, staples and
wire from the tree.
2. Make a notch 1/3 the diameter of the tree,
perpendicular to the direction of the fall. (Fig. 57)
3. Make the lower horizontal notch cut. This will prevent
either the saw chain or the guide bar from being
pinched when the second notch is made.
4. Make the felling back cut (X) at least 50 mm (2 in)
higher than the horizontal notching cut. Keep the
felling back cut parallel to the horizontal notching cut
so enough wood is left to act as a hinge. Do not cut
through the hinge. The hinge wood keeps the tree
from twisting and falling in the wrong direction. (Fig.
58) (Fig. 59)
5. As the felling back cut nears the hinge, the tree
starts to fall. Make sure that the tree can fall in the
correct direction and not rock rearward and pinch the
saw chain. Stop the cut before the felling back cut is
complete to prevent this. Use wedges of wood,
plastic or aluminium to open the cut and let the tree
fall along the necessary line of fall. (Fig. 60)
6. When the tree begins to fall, remove the product
from the cut, stop the engine, put the product down,
then use the retreat path planned. Be alert for
overhead limbs falling and watch your footing. (Fig.
61)
To limb a tree
1. Use larger limbs to hold the log off the ground.
2. Remove small limbs in one cut. (Fig. 62)
3. Cut branches that have tension from the bottom to
the top to prevent pinching the saw chain or the
guide bar.

To buck a log
CAUTION: Do not let the saw chain touch
the ground.
If the log is supported along its entire length, cut
from the top of the log (known as overbucking). (Fig.
63)
If the log is supported on one end, cut 1/3 the
diameter from the underside of the log (known as
underbucking) . (Fig. 64)
If the log is supported on both ends, cut 1/3 the
diameter from the top. Complete the cut by
underbucking the lower 2/3 of the log to meet the
first cut. (Fig. 65)
If you buck a log on a slope, always stand on the
uphill side of the log. Cut through the log while you
maintain complete control of the product, then
release the cutting pressure near the end of the cut
while firmly gripping the rear handle and front
handle. (Fig. 66)
